581 Tuesday January 9, 2001. guy@alum.mit.edu. Summary for 0.6 release
583 New Linux libpcap implementation, which, in 2.2 and later
584 kernels, uses PF_PACKET sockets and supports kernel packet
585 filtering (if compiled into the kernel), and supports the "any"
586 device for capturing on all interfaces. Cleans up promiscuous
587 mode better on pre-2.2 kernels, and has various other fixes
588 (handles 2.4 ARPHRD_IEEE802_TR, handles ISDN devices better,
589 doesn't show duplicate packets on loopback interface, etc.).
591 Fixed HP-UX libpcap implementation to correctly get the PPA for
592 an interface, to allow interfaces to be opened by interface name.
594 libpcap savefiles have system-independent link-layer type values
595 in the header, rather than sometimes platform-dependent DLT_
596 values, to make it easier to exchange capture files between
599 Non-standard capture files produced by some Linux tcpdumps, e.g.
600 the one from Red Hat Linux 6.2 and later, can now be read.
602 Updated autoconf stock files.
604 Filter expressions can filter on VLAN IDs and various OSI
605 protocols, and work on Token Ring (with non-source-routed
608 "pcap_open_dead()" added to allow compiling filter expressions
609 to pcap code without opening a capture device or capture file.
611 Header files fixed to allow use in C++ programs.
613 Removed dependancy on native headers for packet layout.
614 Removed Linux specific headers that were shipped.
616 Security fixes: Strcpy replaced with strlcpy, sprintf replaced
619 Fixed bug that could cause subsequent "pcap_compile()"s to fail
620 erroneously after one compile failed.
622 Assorted other bug fixes.
624 README.aix and README.linux files added to describe
625 platform-specific issues.
627 "getifaddrs()" rather than SIOCGIFCONF used, if available.

644 the list of interfaces is read as necessary in order to hold the
647 Greg Troxel <gdt@ir.bbn.com>
